Renovascular hypertension is also known as renal hypertension. This can be defined as a rise in blood pressure because of partial or complete blockage of the renal arteries. It may be caused by a blockage in only one artery or multiple arteries. This condition does not usually exhibit any symptoms unless it is a long-standing condition. Renovascular hypertension may be caused by a narrowing of one or both renal arteries or fibromuscular dysplasia. It can also be affected by kidney disease.
Without treatment, renal hypertension can affect a number of other organs. In extreme cases, it can even be fatal by causing kidney failure, heart attacks or a stroke. Hence, an early diagnosis and treatment is a must. Medication is usually the first form of treatment advised by a person. This takes the form of ACE inhibitors and angiotensin II receptor blockers. However, in some cases, taking both types of medication may still not be enough to reduce renal hypertension. In such cases, surgical procedures may be required. Surgery has longer lasting results and it helps control hypertension to a much higher degree as compared to medication. The results of a surgical procedure are also quicker.
The most common surgical procedures used to treat this condition include:
